AGETYLENE-GASV GENERATOR.

SPECIFICATION formingpart of Letters Patent No. 749,294, dated January 12, 1904.

Application filed March 21, 1903.

1 To all whom it may concern:

3 f the accompanying drawing, which presents a vert cal sectional view through an apparatus Be it known that I, FREMONT L. IRISH, a citizen of the United States, residing at Auburn, in the county of Androscoggin, State of Maine, have invented a new and useful Acetylene-Gas Apparatus, of which the following is a specification. 1

The present invention relates to'improve' ments in acetylene-gas apparatus, and particularly to means for automatically controlling the admission of water to the generator as the supply of gas in the generator is reduced.

The invention resides in the peculiar construction and arrangement of parts, that will be hereinafter described in connection with constructed in accordance with the invention.

2 5 l which may be of any suitable style.

is placed a bell 3.

the bottom of the gasometer and into the bell ometer.

therein, the end of said pipe within said bell terminating in a bent or downwardly-extending section 5, the lower end of which terminates below the level of the water in the gas- The gasometer is provided with a pipe 6, connecting with the service pipe or system and with an escape-pipe 7 the latter being surrounded by a telescoping section 8, attached to the top of the gasometer bell 9 and provided with apertures 10, that, except when the said bell is subjected to an abnormal and excessive gas generation, are beneath the level of water in the gasometer. Said gas-pipe 4 l 1 is provided with a branch 11, that extends into i the bell 12 of an auxiliary or regulating vessel arranged between the generator and gasometer. This bell 12 lsarranged .Within a suitable tank or receptacle 13, similar to the outer tanks of the gasometer and generator,

I and is provided with the usual water seal to Serial No. 148,935. (No model.)

bells 9 12, the end ofsaid pipe within the bell 12 being inclosed by a telescoping tube or hood 15, closed at its upper end. Said hood or telescoping-tube '15 is provided with apertures 16, similar to the apertures in the escape-pipe of the gasometer. The lower end of the hood 15 is shown as extending slightly below the bottom edge of the bell 12, and said lower end of the hood is connected to one end of a lever 17, mounted within the tank 13 be neath said bell. To the other arm of the le: ver 17 is connected a rod 18, that extends upwardly through suitable guides between the tank 13 and bell 12 to a point above the upper edge of the tank and is provided at its upper end with a laterally-extending arm 19. Said arm 19 extends into the path of an arm 20,

' attached to and projecting laterally from the bell 9 of the gasometer.

Water-pipes 21 22 respectively connect the gasometer with the regulatortank and the latter with the generator, said pipes being provided with suitable valves 23 2 1.

' The water-pipe 22, connecting the regulator and generator, has within the latter two parallel sections connected at their upper ends. As shown in the drawing, the highest point of the pipe 22 within the generator is in substantially the same horizontal plane as the upper end of said pipe 22 within the regula's tor and the upper end of the pipe 21 in the gasometer. A series of perforations 26 are provided in the wall of the pipe 22, at or near the highest point thereof, within the generator, the delivery end of said pipe, as shown, being nearthe bottom of the generator.

It will be noticed that the lower end of the pipe 5 is below the upper end of pipe 21 and constantly below the level of water in the bell 9, and consequently the pressure within the bell, 12 will be determined by the depth to which the said pipe 5 is immersed. The pressure in said 'bell 12 will be equal to that of the bell 9 plus the pressure in the pipe i. The pressure within the hood 15, however, is the same as that in the hell 9, with which it is connected by the pipe It. When the generator is charged and ready for use, the water will stand on about the sanie level both the tank 13 and the tank of the gasometer and within the bells in said tanks, say on the level indicated by the dotted line A A. It will be seen that this-level is above the upper inlet end of the pipe 22 and below the apertures 16 in the tube or hood 15. After a certain pressure of gas has been reached in the bells 9 12 the apertures 16 will be moved below the water-level in the bell 12, owing to said hood or sleeve 15 being released from the pressure exerted by the bell 9 through the parts 20 19 17 and said water-level will be below the upper inlet end of the pipe 22, and thereby the supply of water to the generator will cease, although it is to be noted that the said pipe is never gasbound, but always contains a column of water.

The operation of the parts hereinbefore described may be briefly stated as follows: The gasometer and regulator tanks and bells being connected, as described, the water in said tanks will stand at the same level, and when the gasometer contains a sufiicient quantity of gas the level of the water in the regulator will be somewhat below the upper end of the pipe 22, by which water is supplied to thegenerator. When such condition exists, no water will pass through the pipe 22 and the generator will be inactive, although said pipe Will contain a body of water. As the supply of gas in the gasometer is reduced the bell 9 will fall, and when the supply of gas has been reduced to a predetermined extent the descent of the arms 20 and 19 through the rod 18 and lever 17 raises the telescoping tube or hood 15. As the apertures 16 in the hood 15 are raised above the level ofthe water in bell 12 the gas contained in said bell escapes to the gasometer and the water rises in said bell until it reaches and overflows the upper end of the water-pipe 22. The generator is thus set in action andthe gas generated therein escapes through the pipe 41 and its branch 11 to the bells of the gasometer and regulator. VVater will continue to flow through the pipe 22 and the generator be maintained in action until the gas in the gasometer-bell is again at the desired maximum pressure, when the arms 20 19 will be at such an elevation that the apertures 16 will be below the water-level in the regulator and said water-level will be below the'upper end of the pipe 22'.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In an acetylene-gas apparatus, the com= bination with a generator and a gasometer connected to the generator to receive gas therefrom, of a regulator interposed between the generator and gasometer and including a tank, which is connected with the tank of the gasometer, and a vertically-movable bell, a gaspipe extending from the generator to the regulator-bell, a second gas-pipe extending from said bell to the gasometer, a hood inclosing the end of the last said pipe within the regulator-bell, a pipe for supplying water to the generator having its inlet end within said bell of the regulator, and means whereby motion of the gasometer-bell is transmitted to the said hood within the bell of the regulator and the supply of water to the generator automatically controlled.
